As one of the initial ten charter agencies incorporated in Canada in 1960,

Big Brothers Bigs Sisters of Grey Bruce and Western Simcoe (BBBSGBWS) has been serving youth and families throughout the community for over 60 years. Transitioning to Big Brothers Big Sisters of Owen Sound in 2016, then expanding our reach in 2019 to Grey and Bruce, and again increasing our catchment in 2021 to include Western Simcoe, we are proud to have deep roots. As a mentorship organization, we believe in investing in the power and potential of all youth and our mentorship programs do just that. With both community-based and in-school programs, we ensure children and youth are supported to overcome adversities and increase resiliency across time.


At Big Brothers Big Sisters Grey Bruce and Western Simcoe (BBBSGBWS), we believe working towards equity, diversity and inclusion involves an ongoing commitment that starts with active listening, reflection and action. Our vision is communities free of discrimination where all young people are empowered to realize their full potential. Our members believe in the dignity and worth of each individual and regard the welfare of the community we serve as our primary obligation. At BBBSGBWS, we are committed to ongoing personal development and professional growth, and as an organization, pledge to leverage our platform and utilize our programs to support the potential of all youth, in all communities throughout Grey and Bruce and Western Simcoe.

BBBSGBWS believes we are strengthened by diverse perspectives, backgrounds and experiences and we welcome input from all members of the community.


BBBSGBWS acknowledges with respect to the Indigenous Peoples whose traditional territory we reside, the Haudenosaunee, Ojibway/Chippewa and Anishnabek peoples. We acknowledge our collective responsibility to accountable relationship building and meaningful acts of reconciliation.

Championing the health and wellbeing of youth

To create communities where young people belong and are empowered to unlock their potential.


Provide one-to-one and group mentoring programs that foster growth and build community.


Big Brothers Big Sisters of Canada is a Federation comprised of 91 member agencies servicing more than 1,100 communities across the country.


Many children and youth in Canada struggle with societal barriers and face adversities in their lives.


Facing prolonged adversity creates toxic stress in the brain that can negatively impact development.


With the support of a mentor, these risks can be reduced or even avoided, and youth can reach their full potential.

Our Solution

Many children and youth in Canada struggle with societal barriers and face adversities in their lives like detrimental living conditions, family violence, risk factors for mental health, school issues and identity challenges.

These circumstances have nothing to do with the value of who they are or who they can become, but because of these situations, children and youth risk not having the opportunity to live up to their full potential.

Even worse is the possibility of continuing cycles of poverty and crime or developing mental health issues. This comes at a cost to the young person, and to society.

With the guidance and support of a mentor, these risks can be reduced or even avoided, and youth are reminded they can be anything they dream of being.

Big Brothers Big Sisters of Canada is a Federation comprised of 102 member agencies servicing more than 1,100 communities across the country. Together we mobilize over 20,700 volunteers who in turn mentor 41,400+ children and young people.

Theory of Change

Big Brothers Big Sisters works on a Theory of Change as the foundation for all of our programming and mentoring efforts. 

Our Theory of Change centers on the transformative influence of one-to-one mentoring relationships in empowering young people. By fostering enduring connections between adult volunteers (“Bigs”) and youth (“Littles”), the organization aims to create positive, long-term impacts. Grounded in evidence-based practices, the approach emphasizes a child-centered perspective, recognizing each mentee’s unique strengths and challenges. Through this personalized support, Big Brothers Big Sisters seeks to boost self-esteem, academic achievements, social skills, and emotional well-being, ultimately guiding young individuals towards fulfilling their full potential. 

To achieve lasting change, Big Brothers Big Sisters also emphasizes the importance of a supportive ecosystem. Engaging families, schools, communities, and other stakeholders, the organization strives to create an environment that nurtures the growth of its mentees. Continuous learning and adaptation are integral components of the theory, as the organization continuously evaluates its programs, gathers feedback, and adjusts to meet the evolving needs of the youth it serves. By investing in sustained mentoring relationships and committing to evidence-based practices, Big Brothers Big Sisters remains dedicated to breaking down barriers and empowering young individuals to lead successful, fulfilling lives. 

1.2 million volunteer hours each year

Each Big Brother Big Sister agency provides direct service to children by matching volunteers and youths in quality mentoring relationships. Our agency staff members are experts at screening volunteers and matching them with a mentee having similar interests.

The national organization provides services and programs to our member agencies to assist them with their work with parents, mentees, and volunteers. Ranging from staff training workshops to our leading Child Safety Program, Big Brothers Big Sisters of Canada works diligently to ensure we have superior quality programming in all parts of the country.
